SELF-SEALING BOTTLE" Specification of Letters Patent.

Patented April 10, 1906.

Application filed May 4, 1905. Serial No. 258.868.

To 6t whom it may concern;

Be it known that I, WVILLIAM A. MILLER, a citizen of the United States, residing in Boston, in the county of Suflolk and State of Massachusetts, have invented certain new and useful Improvements in Self-Sealing Bottles, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to improvements in self-sealing bottles suitable for holding proprietary beverages and other fluids and provided with devices located in the neck of the bottle, permitting it to be emptied, but not refilled.

The object of my invention is to produce a self-sealing bottle capable of manufacture on a commercial scale that is, one which is not so difficult to make as to be beyond the reasonable cost of such an article.

Bottles have been; proposed which require such extraordinary care of the glass-blower that the cost is excessive. This is particularly true of bottles having interflowing ducts formed in the bottleneck to coact with inserted parts of the sealing devices. For this reason I have made my sealing device containing the ducts or fluid-passages as an integral plug that may be easily molded, which, after filling the bottle, is permanently fastened into the neck of the bottle.

My invention consists in a bottle having a series of fluid-seals and an obstruction or plug in the neck of the bottle provided with interiilowing channels, which plug prevents tampering with the seals or valves controlling an attempt to refill the bottle, and the invention further consists of the devices and arrange- :ment of parts to be more particularly set out.

The drawings show in Figure l, a longitudinal sectional view of a bottle-neck containing my self-sealingdevice Fig. 2, a cross-section of the neck at the line a; as, as in Fig. 1 Fig. 3, a cross-section of the neck at the line 1 y of Fig. 1; Fig. 4, a cross-section of the neck at the line .2 z of Fig. 1 Fig. 5, an elevation oi the plug; Fig. 6, an elevation of the bottleneck with a portion of the bottle broken in section at the junction with the said neck.

The bottle is made of any suitable mate rial which is not afl'ected by water or alcohol, and is of any shape desired up to the neck. At the junction of the neck with the body of the bottle a seat a is formed, which is covered by a ball b. Above this ball the neck is bulged the seat d, which is covered by the disk 6. This disk is usually made of mica, and it is held to its seat by a weight f of any suitable material. The neck of the bottle is contracted above the chamber 0 to guide the weight f, and to allow the liquor to flow easily by the mica-disk 6 channels g are blown lengthwise of the chamber 0, which channels project beyond. the walls of the said chamber. A plug h, which is of unusual construction, is fitted tightly in the neck of the bottle above the weight f. My preferred construction for securing the plug in the bottle consists in blowing several longitudinal grooves i in the neck of the bottle, which turn at right angles to run, as at j, around. the bottle, the grooves gradually decreasing in depth as they depart from the longitudinal portion. The upper portion of the plug is formed with several teeth, as is, projecting radially outward from the elongated body portion of the plug, and beveled lugs Z at the peripheries of the teeth enter the grooves i as the plug is inserted in the neck of the bottle. Then the plug is given a sharp turn with a wrench and the lugs follow along the grooves j until they jam tightly against their wedge-shaped faces. Cement may be applied. to the lugs and grooves to insure a permanent joint. Between the teeth k of the plug wide ducts m are provided. in the plug for the liquor, and to prevent the insertion of awire to tamper with the disk or ball valves the baffles "a are located below and in line with the ducts m. Between the baffles channels 0 are provided, leading from the valves in an axial direction and connecting through the horizontal groove 1), located between the baffles n and the teeeth is with the ducts m. The lower por tion {I of the plug tapers to a tip, which enters a cavity 8 in the weight The bottle is first filled with liquor and the ball I) is dropped on the seat d. Then the mica disk 6 is doubled and pushed down to the seat (1 of the chamber 0. The weightf is now dropped on the disk 6, and finally the plug is inserted and locked. by the bayonetjoint, formed by the grooves i and j in connection with the lugs Z of the plug. The arrangement of the elements of the plug, as described, as an integral structure which may be molded is of great importance, as channels of ample proportions are thereby provided for the liquor, which is a difficult matter if the channels are to be blown in the bottle.

outward, forming a chamber 0, containing i The ducts m, through whiehthe liquor passes to the neck t of thebottle, are of considerable cross-section to break up any gushing or spraying of the liquor as it issues from the neck of the bottle, due to the choking of the entering air through the angular channels and fluttering valves.

Having described my invention, I claim and desire to secure by Letters Patent of the United States In a self-sealing bottle, the bottle-neck, means within the bottle-neck permitting escape but preventing inflow of fluid to the bottle, and devices in the neck of the bottle constituting one member of a bayonet-j oint, combined with a plug in the neck of the bottle,

teeth radiating from the plug toward the wall of the bottle-neck, lugs projecting from the witnesses. v
